Radiotherapy News and Research

RSS

Radiation therapy (in North America), or radiotherapy (in the UK and Australia) also called radiation oncology, and sometimes abbreviated to XRT, is the medical use of ionizing radiation as part of cancer treatment to control malignant cells (not to be confused with radiology, the use of radiation in medical imaging and diagnosis).

DNA’s Role in Glioblastoma: Insights from Umeå University’s Research

A groundbreaking research conducted at Umeå University in Sweden has revealed that the three-dimensional arrangement of DNA can impact the development of aggressive brain cancer, glioblastoma.

Revealing the Link Between Radiation Damage and DNA Rupture Time

Investigators from the University of Trento’s Physics Department discovered a link between the effect of radiation on DNA and the time when the damaged molecule breaks irreversibly.

Analyzing DNA Damage-Induced NF-κB Targeted by Novel Small Molecule Inhibitors

Chemotherapy and radiotherapy aim to destroy cancer cells by inducing DNA double-strand breaks – damage that, once inflicted, usually causes the cells to die. But damage to a cell's genetic material also activates a signaling pathway called IKK/NF-κB that helps prevent cell death, thus limiting the success of these treatments in patients.

Research may Offer a New Way to Break Through Cancer's Hypoxia-Induced Defenses

For most of our tissues and cells, a lack of oxygen, or hypoxia, is bad news. Cancer cells, on the other hand, can thrive in these hypoxic conditions, which render tumors less susceptible to anti-cancer treatments, including radiation.

Analyzing the Role of Pyroptosis in Improving the Treatment of Lung Cancer

Lung cancer, one of the most aggressive forms of cancer, continues to be a leading cause of death worldwide. Although several new therapies have been developed for this disease, it has a poor prognosis in its advanced stages.

Cancer cells use new DNA repair mechanism to recover from next-generation cancer radiation therapy

A team of scientists led by Dr. Kei-ichi TAKATA from the Center for Genomic Integrity within the Institute for Basic Science (IBS), has discovered a new type of DNA repair mechanism that cancer cells use to recover from next-generation cancer radiation therapy.

Using nanoparticles to carry drugs across the blood-brain barrier

Brain tumors are notoriously hard to treat. One reason is the challenge posed by the blood-brain barrier, a network of blood vessels and tissue with closely spaced cells.

Analyzing the immune microenvironment around Hodgkin lymphoma tumors

The most detailed study of Hodgkin lymphoma, a type of blood cancer, has offered considerable insight into what tumor cells must do to sustain. The Wellcome Sanger Institute discovered that cancer cells utilize signals to attract specific types of immune cells and direct them not to attack.

Molecular staple: The DNA repair mechanism impeding cancer treatment

Due to the continuous cellular activity, malfunctions frequently occur, making error-correcting systems crucial for cells. However, it serves the cancer cells’ best interests to cause errors when it comes to destroying them.

Predictive classifier identifies patients who can skip radiation therapy

According to the findings of a meta-analysis proposed at the San Antonio Breast Cancer Symposium held on December 6–10th, 2022, patients with invasive breast cancer who had low scores on an investigational gene molecular signature seemed to have similar rates of local recurrence regardless of whether they received adjuvant radiation therapy after breast-conserving surgery.

New bioprinting platform to replicate tumors in 3D spheroids

Bowel cancer patients could in future benefit from a new 3D bioprinting technology which would use their own cells to replicate the complex cellular environment of solid tumors in 3D models.

Radiation therapy can reprogram heart muscle cells to a younger state, suggests study

New research from Washington University School of Medicine in St. Louis suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure.

Researchers find a new way to counter immunosuppressive effect in tumors

Malignant tumors can enhance their ability to survive and spread by suppressing antitumor immune cells in their vicinity, but a study led by researchers at Weill Cornell Medicine and NewYork-Presbyterian has uncovered a new way to counter this immunosuppressive effect.
